Engineered for Speed

You want protection that won’t slow you down. This year our engineers evaluated every line of code, every possible interaction in our products with the goal of providing you security that is the fastest and lightest available.
Faster & Lighter

How we save you time

Installation

Our new installer gets you going with one click and in less than one minute.*

Memory Utilization

Uses less than 6 MB of memory on average between system scans so your primary applications won’t be competing for resources.**

Boot Time

Adds less than 3 seconds to boot up time for the average PC and less than 1 additional second to open the browser — to get you online fast.**

Scan Time

Our scan speed is 81% faster than the competition so you don’t spend time waiting for your PC to finish scanning.**

What does “Faster & Lighter” mean?

Faster & Lighter means security that won’t slow you down. More specifically it means faster, fewer and shorter scans, high-speed network throughput, one-minute install*, fewer active processes, less memory utilization – in general faster operations so you won’t feel a performance impact on your day-to-day computing experience.

How performance affects a typical day using your PC.

Passmark, an independent testing lab, tested the performance of our Norton AntiVirus and Norton Internet Security 2009 products and compared the results to the performance of some of our competitors. They tested scan speed, boot time, and network throughput for download speeds using a standardized PC configuration running a security product. The results speak for themselves.**
